An interview with Alfredo Carpineti

Posted in LGBT, Uncategorized on April 29, 2016 by telescoper

Ooh. I’ve just noticed this so thought I’d reblog it.

Dr Carpineti did the London Marathon last weekend too!


Current Job:  Science JournalistAlf

Scientific Discipline/Field: Astrophysics

Country: UK

Pick some letters (L,G,B,T,Q etc.): G


What does your job involve?

I work for ‘I fucking Love Science’. I write three articles a day about new research being published, mainly on physics and astrophysics.

How did you get to this job (education etc.)?

I have a B.Sc. from La Sapienza, Rome, an M.Sc. in quantum fields and fundamental forces and a Ph.D. in astrophysics both from Imperial College London.

Do you feel being LGBT has affected your career decisions?

Yes, I felt I couldn’t really be myself in Italy so I decided to move to London to continue my studies.

Have you had any reactions from colleagues about being LGBT, either good or bad?

The reactions to my sexuality have mostly been good. I’ve never had a bad reaction personally, but I know of somebody, another Ph.D…

Happy Retirement, Diane Greening!

Posted in Uncategorized on April 29, 2016 by telescoper

Yesterday’s retirement do reminded me that I had neglected to mention another retirement, this time from the Science and Technology Facilities Council.

Diane Greening is retiring at the end of this month from her position at STFC where, among many other things, she provided valuable support and guidance to the Astronomy Grants Panel. I’ve served on that panel myself and I can tell you it’s no picnic, not least because there’s just not enough money to go around so many applicants are bound to be disappointed. Those long and difficult meetings in Swindon would have been even tougher without the patience and good humour of the office team, especially Diane.

I’m sure I speak for everyone in the UK Astronomy community when I say thank you to Diane for her sterling service at STFC and wish her a very long and very happy retirement!


A Problem in Lagrangian Mechanics

Posted in Cute Problems with tags , , on April 28, 2016 by telescoper

Today, as well as saying goodbye to Sally Church, I managed to finish my lecture course on Theoretical Physics. There’s still another week of teaching to go, but I have covered all the syllabus now and can use the remaining sessions for revision. The last bit of the course module concerned the calculus of variations and a brief introduction to Lagrangian mechanics so for a bit of fun I included this example.

Professor Percy Poindexter of the University of Neasden has invented a new theory of mechanics in which the one-dimensional motion of a particle in a potential V(x) is governed by a Lagrangian of the form

L=mx\ddot{x} +2V(x).

Use Hamilton’s Principle and an appropriate form of the Euler equation to derive the equation of motion for such a particle and comment on your answer.

UPDATE: Since nobody has commented I’ll just reveal the point of this question, which is that if you follow the instructions the equation of motion you should obtain is

m\ddot{x}= -\frac{\partial V}{\partial x},

which is exactly the same as you would have got using the usual Lagrangian

L= \frac{1}{2}m\dot{x}^{2} - V(x).

Anyone care to comment on that?

Happy Retirement, Sally Church!

Today marks the end of an era for the Department of Physics and Astronomy at the University of Sussex. Sally Church, pictured below, is retiring today after over 27 years in the Department (and almost 29 in the University). No doubt there are many readers of this blog who have passed through Sussex at one time or another and met Sally. In fact, she arrived in the Department when I was here in a previous incarnation as a PhD student in the late Eighties and was still here when I returned in 2013 as Head of School. She recently received a long service award from the University in recognition of her loyalty and hard work.

Sally Church

Sally has been our Course Coordinator for Physics and Astronomy and, as such, has been a key member of our office team, providing administrative support for a huge range of teaching and other activities. She will be extremely hard to replace as her understanding of the University’s systems and procedures is second to none, but she’s definitely earned a rest and on behalf of everyone in the Department, the School and the University as a whole I wish her a very happy retirement!

P.S. Shortly, at 2.30pm, there’s going to be a farewell gathering, with speeches and gifts, at which I hope to take a few pictures which I’ll post here later.

P.P.S. I only had time to take one picture, but here is Sally opening some of her gifts among the remains of the cakes and scones…


What has the European Convention on Human Rights ever done for us?

Posted in Politics with tags , , on April 27, 2016 by telescoper

In case there are some people who haven’t seen this yet, here is a short video featuring Sir Patrick Stewart the Guardian made in response to Home Secretary Theresa May’s suggestion that the United Kingdom should leave the European Convention on Human Rights. It owes more than a little to Monty Python’s Life of Brian but is none the worse for that. Make sure you watch right to the end as it exposes the hypocrisy of Home Secretary’s position on this.

What’s the point of ResearchGate?

Posted in Biographical, The Universe and Stuff with tags on April 26, 2016 by telescoper

Some years ago, in a moment of weakness, I joined a website called ResearchGate. I’m not sure why, but it seemed a good idea at the time. I don’t visit the actual site very often, but it does send me large numbers of emails. Normally about things I’m not particularly interested in or asking me if I’m an author of a paper about biochemistry they’ve found somewhere on the net. Once a week I get one like this:


I get a similar one every week without fail. It’s always flattering to be thought of as being in the spotlight, but the obvious inference to be made from the fact that I get such a message every week is that I am the only person in the Department silly enough to have joined ResearchGate.

Has anyone out there joined ResearchGate and found it worthwhile? Maybe there’s something worthwhile about it?

Do tell.

Nothing Compares

Posted in Biographical, Music with tags , , on April 25, 2016 by telescoper

For some reason I just remembered this morning that a song that is full of nostalgia for me was written by Prince, who died last week. The version I still have on vinyl was a huge hit for Sinead O’Connor in 1990:

Incidentally, I once saw Sinead O’Connor in person at the Zap Club in Brighton during my previous incarnation here as a research student and postdoc. I literally bumped into her trying to get to the bar to buy a drink. When she turned around I was staggered to see such a beautiful face looking at me, although to be honest I did for a moment assume she was a boy. It was, I should explain, a gay night at the club. Fortunately she was very nice and friendly and forgave my clumsiness with a gracious smile.

There aren’t many any other pop videos done like this, almost entirely in close-up. Can anyone think of any others?
